Abstract


This study aims at finding out the availability of N, P, and K nutrients and soil organic C rate due to the application of organic matter (Gamal leaf, banana stem, and banana peel). This study is conducted in Kedai Organik, Gorontalo City. Randomized Group Design is applied in this study, consisting of 4 treatments and 10 repetitions. P0 is control (without liquid organic fertilizer). P1 is 70 ml Gamal leaf liquid organic fertilizer, 100 ml banana stem, and 120 ml banana peel. P2 is 120 ml Gamal leaf liquid organic fertilizer, 70 ml banana stem, 100 ml and banana peel. P3 is 100 ml Gamal liquid organic fertilizer, 120 ml banana stem and 70 ml banana peel. The result concludes that the N and P rate on one week prior to fertilizer wash very high. After 42 days of observation and at the same time as the harvest time for the lettuce plants, the N rate was low, P rate was high, K was high, medium, and low the C-organic was averagely high, medium, and low
